Abstract

594261 Disclosed is a method for treating raw water laden with impurities in a treatment facility including at least one step of placing water in contact with a powdered adsorbent agent in an agitated pre-contact area (2), a step of ballasted flocculation, a step of settling, extracting a mixture of sludge, ballast and the powdered adsorbent agent from the bottom of the settlement area (5), and inserting the mixture in a hydrocyclone (11), transporting the overflow consisting of a mixture of sludge and powdered adsorbent reagent from said hydrocyclone (11) to a transition area (14). The method also includes a step of recycling the mixture of sludge and powdered adsorbent agent from the transition area (14) in the pre-contact area (2), continuously measuring at least one datum showing the concentration of powdered adsorbent agent in the pre-contact area (2), and a step of injecting a suspension of new powdered adsorbent agent in an aqueous medium upstream when the concentration of powdered adsorbent agent in the pre-contact area (2) is below a predetermined threshold value, as well as a step of acidifying said suspension of adsorbent agent.
